Comment 13 for bug 56939

That's alright, thank you for bug triaging ;)

The glib package is not known to be broken on dapper and other users would have opened bugs before if it was. The bug mentions "libglib2.0-dev: Depends: libglib2.0-0 (= 2.10.2-1ubuntu3) but 2.10.3-0ubuntu1 is to be installed", could you run "apt-cache policy libglib2.0-0 libglib2.0-dev libartsc0-dev"? It looks like libglib2.0-0 has been installed from dapper-updates and that you removed the updates source and it can't find the matching libglib2.0-dev version now
